DRAFT-RIGGING FORv RAILWAY-CARS.

SPECIFIGATXON forming part of Letters Patent No. 668,655, dated February26, 1901.

Application filed February 24, 1900. Serial No. 6,358. iNo model.)

To all whom t may concern.-

Be it known that I, WILLIAM H. MINER, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Tandem-Spring Draft-Rigging forRailway-Cars, of which the following is a specification.

My invention relates to improvements in tandem-spring draft-rigging forrailway-cars.

My invention consists in -the novel construction of parts and devicesand in the novel combinations of parts and devices herein shown anddescribed, and specied in the claims.

In the accompanying drawings, Figure lis a plan view of a draft-riggingembodying my nvention.- Fig. 2 is a central longitudinal section, partlyin elevation. Fig. 3 is a front view, the draw-bar and coupler beingremoved. Fig. 4 is a cross-section on line a; x of Fig. 2. Fig. 5 is across-section similar to Fig. 4, showing a slight modification inconstruction; and Fig. 6 is a detail perspective view of one of thestop-castings.

In the drawings similar letters of reference indicate like partsthroughout all the figures.

In said drawings, A represents the steelbeam end sillof a steelcar-frame, and B B steel draw-beams, the same being preferablychannel-beams, with their anges b turned outward, thus leaving the steeldraw-beams with plain or smooth inner faces b'.

C is a metal yoke having its two sides securely riveted to the steelchannel drawbeams B.

D D are the draw-bar stop-castings, each furnished with end stops d2 d2and a deeper middle stop d and an upper integral follower guide orflange d3, having tapering edges d4 d4 extending from the middle stop tothe two end stops. These stop-castings abut at their rear ends againstthe cross-bar C' ofY the yoke C and are secured by bolts d5 to the steelchannel draw-beams, the bolts extending through the yoke C, as well asthe drawbeams and stop-castings.

E is the coupler, E' the draw-bar, and F the draw-bar extension orpocket-strap secured rigidly to the draw-bar by the bolts f andinterlocking shoulders f'f2 on the draw-bar and pocket-strap.

G is the abutment-block, -rigidly secured to the pocket-strap by thebolt or rivet g.

H h H h are tandem-arranged springs, and K K K2 K3 are the followers.

D is a steel plate which serves as the lower guide for the followers,the same being secured at its opposite edges to the steel drawbeams bybolts d6, which extend through the lower flanges b of the steel channeldrawjbeams B B. This guide-plate D serves to rigidly tie togetherandbrace the two steel draw-beams and also as a guide for the followers andalso as a support for the draftrigging as a whole. It is furnished witha central longitudinal channel Z7 for the-lower member of thepocket-strap. Owing to the inclined inner edges d4 of the guide-'fianged3 of the stop-casting and the greater depth of the middle stop d overthat of the end stops 0lz a fulcrum is formed at the angle of saidinclined edges for the draw-bar pocket-strap to swing or turn upon, as.required when the train is passing around curves. Bolts d8 may alsopreferably extend through the bottom plate D and the stops of thestop-castings. The yoke C also, preferably, is furnished with gibs orshoulders C2 for the front ends of the stop-castings to abut against.

I claiml. In a tandem-spring draft-rigging, the combination with a pairof iianged steel draftbeams, of a yoke C secured thereto, a pair ofstop-castings D D secured within said yoke and furnished each with threeintegral stops, and an upper guide or ange tapering from the middletoward each end, the middle stop being deeper than the end stops, twotandemarranged springs, followers at l[he ends of said springs andabutting against said stops, a draw-bar and pocket-strap, and a lowerguide-plate D removably secured by bolts eX- Iending through the lowerflanges of said steel draft-beams and provided with a centrallongitudinal channel for the lower member of the pocket-strap,substantially as specified.

2. The combination with the draw -bar, pocket-strap, tandem-arrangedsprings and followers, of a pair of flanged steel draftbeams, a pair ofstop-castings secured thereto, and fitting between the inner facesthereof, bolts passing-horizontally through said IOO stop-castings andsaid beams, each of said stop-castings being furnished with three stopsand upper guide-fiange extending between said stops, a lowerguide-plateextending from the front to the rear follower for the followers and thedraft-rigging to rest upon and extending between said draft-beams andsecured thereto by bolt-s passing through the lower fianges thereof,substantially as specified.

3. The combination with the draw-bar, pocket-strap, tandem-arrangedsprings and followers, of a pair of flanged steel draftbeams, a pair ofstop-castings secured thereto, and fitting between the inner facesthereof, bolts passing horizontally through said stop-castings and saidbeams, each of said stop-castings beingfurnished with three stops andupper guide-flange extending between said stops, a lower guide-plateextending from the front to the rear follower for the followers and thedraft-rigging to rest upon and eX- tending between said draft-beams andsecured thereto by bolts passing through the lower fianges thereof, saidguide-plate having a central longitudinal channel for the lower memberof the pocket-strap, substantially as specified.

4. The combination with the draw-bar, pocket-strap, tandem-arrangedsprings and followers, of a pair of hanged steel draftbeams, a pair ofstop-castings secured thereto, and each furnished with three stops andupper guide-liange, a lower guide-plate for the followers and thedraft-rigging to rest upon extending between said draft-beams andsecured thereto by bolts passing through the lower flanges thereof, theupperguide-flanges of said stop-castings each tapering from the middletoward both ends to form a fulcrurn for the pocket-strap to swing upon,substantially as specified.

5. The combination with the draw-bar,

pocket-strap, tandem-arranged springs and followers, of a pair offlanged steel draftbeams, a pair of stop-castings secured thereto, andeach furnished with three stops and an upper guide-flange, a lowerguide-plate for the followers and the draftrigging to rest uponextending between said draft-beams and secured thereto by bolts passingthrough the lower flanges thereof, said guide-plate having a centrallongitudinal channel for the lower member of the pocket-strap, the upperguideflange of said stop-castings each tapering from the middle towardboth ends to form a fulcrum for the pocket-strap to swing upon,

substantially as specified.

6. The combination with the draw bar, tendem-arranged springs andfollowers, of a pair of draft-beams, a yoke C secured thereto and havingcross-bar C', a pair of stopcastings D D secured within said yoke andfurnished each with three stops for the followers to abut against, therear ends of said stop-castings abutting against said cross-bar C ofsaid yoke, substantially as specified.

7. The combination with the drawbar, tandem-arranged springs andfollowers, of a pair of draft-beams, a yoke C secured thereto, a pair ofstop-castings D D secured within said yoke and furnished each with threestops for the followers to abut against, said yoke having gibs orshoulders at its front ends for the front ends of the stop-castings toabut against, and bolts extending horizontally through said draft-beams,yoke and stop-castings, substantially as specified.

8. The combination with the draw bar, tandem-arranged springs andfollowers, ol' a pair of steel draft-beams, a bar C secured thereto, apair of stop-castings fitting against said bar C and abutting at theirfront and rear ends against shoulders or abn tinents with which said baris provided, Said stop-castings being each furnished with three stopsand an upper guide-flange, and bolts passing horizontally through saiddraft-beams, bar C and stop-castings, substantially as specified.
